| SPD Engine System Options |
Specifies the minimum size that the data component partitions
can be. The value is specified when the SPD Engine data set is created.

specifies the minimum partition size in bytes, kilobytes,
megabytes, or gigabytes. The maximum for the minimum partition size is 8,796,093,022,207
megabytes.
| Restriction: |
This restriction applies to 32-bit
hosts only with the following operating systems: zOS, Linux SLES9 x86, and
the Windows family. In SAS 9.2, if you create a data set with a partition
size greater than or equal to 2 gigabytes, you cannot open the data set with
any version of SPD Engine before SAS 9.2. The following error message is written
to the SAS log:
ERROR: Unable to open data file because its data
representation differs from the SAS session data
representation. |
Specifying MINPARTSIZE= sets a lower limit for the
partition size that can be specified with the PARTSIZE= option. The MINPARTSIZE=
specification could affect whether the partitions are created with approximately
the same number of observations. A small partition size means more open files
during processing. Your operating system might have a limit on the number
of open files used.
